To all whom it may concern.

Be it known th'at I, ERLE K. BAKER, a citizen of the United States, residing at Chicago, in the county of .Cookand State'of Illinois, have invented certain new and useful Improvements in StartingDevices for Internal-Combustion Engines, of which the following is-a specificationj This invention relates to engines and particularly to such'as make use of a number of cylinders.

The invention has for its object to enable the starting of such engines without the 15.

necessity of crankingthem, or without the necessity of'rnaking use of other mechanical means, and without the necessity of using the inherent expansive qualities of gas,

stored under pressure.

The invention further relates particularly to automobile engines although it may be evident from a study of this. specification and drawings that it is in no wise limited 'tosuch use.

In the drawings, Figure 1 shows a four cylinder automoblle engine 1n elevation,

looking toward that side of the same to which the inlet and exhaust pipes are connected, and showing my improved starting devices; attached to the same, portions of the storage tanks being cut away; Fig. 2 is a plan view, showing the engine of Fig. 1 having attached to it the same devices as are shown in Fig. 1; Fig. 3 is a detail of the end portion of one of the storage tanks and the adjacent connections; Fig.4 is a detail section of the explosion actuated compressor pump; and Fig. 5 is a detail of the preferred form of check valve for use in the supply pipes.

'In the drawings, the engine 7 having cylinders 8, 9, 10, and 11, is provided with a carbureter, or other suitable mixer 12, sup ply pipes 13 and14, and exhaust pipes 15, 16, 17, and 18 suitably connected to an outlet pipe 19.

The gas pump 20 has its suction pipe 21 connected ',to one of the supply pipes so that the pump will draw an exploslve mixture which has been previously generated inthev carbureter. The delivery pipe 22 from the check valves be placed in the individual conv novel and efiic1ent means for starting internal combustion the preferred form of nectio'ns to the tanks, and for that reason, i

the check valves 28, 29, 30, and 31 are provided. These will prevent a, backward movement of gas from the storage tanks; thus insuring that the same will always be filled with the explosive mixture under pressure. The storage tanks are individually connected to the several cylinders by means of pipes 32, 33, 34, and 35, check valves 36,.

37 38, 211K139 being placed in these pipes to prevent any back fire from the cylinders from communicating with the storage-tanks.

The several pipes 32, 33, 34, and 35 are connected, respectively, to the explosion chambers iof the cylinders throughthe means of valves 40, 41, 42, and 43 which latter may be connected together by means of a rod 44 which may bein communication with a suitable handle at the dash board so that the operator can open all of the valves simultaneously to permit explosive gas'to enter all of the cylinder explosion chambers at the sametime. When the operator has thus allowed the explosive gas to be ad mitted .into'all of the explosion chambers, it is evident that the application of a spark, or other igniting agency, 'to the engine will explode the charges in proper order, so .as to insure that the engine will be started and the necessity of cranking it will be, thereby, eliminated.

As previously indicated, the check valves 36, 37, 38, and 39 serve to' prevent the back fire from the cylinders from communicating with the inflammable mix'ture contained in the several storagev tanks. These check valves furthe r serveto maintain compres sion wlthm the cylinders while the valves- 40, 41, 42, and 43 are open. A'relief valve ferred ,form of compressor. The lower portion of the pump is connected" to theexhaust chamber of the engine '46 b 1 means of'a thimble 47 or in any other su table manner. The numeral 48 indicates the exhaust valve of the engine. 'The body 49 01 the compressor is provided with a neck 50, which isv threaded onto the thimble 47 so that the passageway 51 is in direct communication with the exhaust chamber46, piston 52 working in the body portion of the compressor' has connected to its upper end a compressor piston-"53 which in turn works within a chamber'54. This last piston'53 is preferably of smaller diameter than the piston 2 sothat it will be possible, when desired, to secure a high degree of compresslon. A spring55 surrounding the piston 53 tends to restore the same into lower position' after each upward thrust on the piston 52. A suction pipe 21 connects with'the compression chamber 54 through acheck valve 56, and the discharge pipe 22 connects with' the compression chamber through a cheok'valve 57.

The mode of operation of this explosion actuated compressor is as follows: The valve 40 being closed, the explosion pressure com-.

municates through the passage 51 withvthe lower face of the piston 52. This piston bev ing forced upwardly carries withit the piston 53, thereby compressing the gas in the space 54, forcing the valve 56 to close, and expelling the charge "of gas through thevalve 57 into the discharge pipe22. The pressure within the chamber 46 being relieved by the opening of the valve 48 permits the piston 52 to be forced downwardly by the spring, thereby lowering the piston 53, closing-the valve 57, and drawing a charge of gas into the space 5% Such op- QIat-IOII of the compressor will attend each. spccesslve explosion occurring within the cylinder to which the compressor is at tached.

In Fig; 8, I show more in detail the pre- .ferred' eonnections to the end of each storage'tank -In this case, the. check valve 31 connects with anipple-58, which nipple :in

turn is connected onto one'of the straight line connectors 59, and the other straight line 7 connection of y the samev connecting through the medium of a nipple 60 with the corresponding tank, while the right-angle connect-ion'connects to the cylinder supply pipe32' through the medium of a union con-' necti on 61f 4 ,In 5, I show the preferred form of rotten check valve for use in the cylinder supply pipes. The same comprises a body portlon 62 having a shoulder 63 against which a check ball 64 contacts. The chamber 65 is of sufficient size to allow the ball to enter it,

and allow gas to pass up around the sides of the ball.v

' Although I have shown and described only one form of engine driven compressor, still it is evident that'any form of compressor driven by the engine itself may be used for drawing explosive mixtures from the carbureter, or one of the associated connections, and delivering it to the storage tanks.

I claim: 1. In a mechanism for starting an internal combustion engine, a compressor adapted .to be driven by the engine, the suction pipe of the compressor connected to the CHI: bureter of the engine, a plurality of 'reservoirs for storing gas under pressure, a connection from the compressor to the reser voirs a connection from each reservoir to a cylinder of the engine and a valve in each connection between the reservoir and the cylinder, substantially as described.-

. 2. In a mechanism for starting an inter- .nal combustion engine, a compressor heat ing its suction pipe suitably connected the, carburetor of the engine, a plurality of described.
